What is the best combo for black cars. Also do you need a PC buffer to get even a better shine than hand waxing? Right now Im just using z5, z2, Some basic shampoo by turtle wax. I dont know it probably sux. Then in between i use eagle one spray on to keep it wet in between washes. What are some of your combos you use to really get the black so so wet and deep shine. Im interested in purchasing new stuff or atleast looking.
